A patient was treated with a therapeutic dose of low-molecular-weight heparin, then required caesarean section immediately following its administration. Reasons for preferring this heparin over unfractionated heparin are acknowledged but not supported for short-term use in an obstetric patient near term.

Whether transfusion is necessary, but not the number of red cell units, can be planned by the effect of haemorrhage on antenatal Hb during delivery by caesarean section complicated by placenta praevia.
